The murder of the Aroyo children was a terrorist attack which occurred on January 2, 1971, in which two Israeli children were killed when Palestinian militants threw a hand grenade into the moving car of the Aroyo family which was touring the Gaza Strip.

The attack, which shocked the Israeli public, was a turning point in the way Israel began relating towards terrorist threats originating from the Gaza Strip. Following the attack Israel launched an extensive counter terror operation in the Gaza Strip.

On Saturday, January 2, 1971, the Aroyo family was touring the Gaza Strip in their car.[1] In the afternoon, when the family began to make their way back home, they got on the wrong road and as a result they passed along the main road north of Gaza City where a 15-year-old Palestinian boy threw a hand grenade through the window of the moving car of the Aroyo family. The hand grenade fell into the back seat where the children and their mother were sitting. The blast immediately killed 4-year-old Abigail. 7-year-old Marc-Daniel was severely injured and later on died from his injury at the hospital. The mother, Preeti Aroyo, was badly injured and needed lengthy rehabilitation and remained disabled from the incident.

Immediately after the incident, The father, Robert Arroyo, attempted to call for help and turned to two young Arab men who witnessed the incident. His pleas were not answered, as it later turned out that these men operated as observers during the attack. Robert Aroyo, who was slightly wounded in the attack managed to turn the car around and reach an IDF checkpoint, before collapsing.[1][4]

The murder shocked the Israeli public mostly due to the severity of the attack. The children were buried in the cemetery of the Mount of Olives in Jerusalem. In their funeral they were eulogized by the IDF Chief Rabbi Shlomo Goren.

Israeli security forces caught the perpetrators – 15-year-old Mohammad Suleiman Al Zaki who originated from the Shuja'iyya neighborhood (who threw the grenade), and his two partners who were 16 and 17 years old, all students of the "Falestin" high school who were recruited by a senior PLO member. Besides murdering the children of the Arroyo family, the attackers also attended in several other attacks and were charged on 18 counts of throwing grenades and for planting explosive devices. Zaki and his accomplices were sentenced by a military court in Gaza to life in prison. Zaki was released from prison in 1985 as part of the Jibril Agreement.[6]

As a result of the attack a curfew was imposed on Gaza city and the highway in which the attack took place was closed for a month. The no-intervention policy which was carried out by the Israeli military in the Gaza Strip since Israel took over the Gaza Strip in the Six Day War (in part as a result of the IDF efforts to focus on the War of Attrition in the Suez Canal region), changed as a result of this incident. The counter terrorism campaign was assigned to the Head of IDF's Southern Command, Ariel Sharon. A security fence was established across the Green Line to prevent infiltrations of militants. Large amounts of IDF forces were transferred into the Gaza Strip. The Gaza Strip was divided into smaller sections in which the Shaked commando force operated intensively against the active terrorist cells.[7] In addition, the reconnaissance unit Rimon was established and acted under the command of Meir Dagan[8] to provide targeted treatment against terror cells. In July 1971 various IDF forces entered the Jabalya and Al-Shati refugee camps. During this counter terrorism operation over a hundred militants were killed in battle and hundreds of militants were arrested.
